Re: Risbecia ghardaqana trailing

Dear Bill,
Concerning the message about Risbecia ghardaqana. Even at the risk of getting on your nerves, why should this one, with the exact outlook of R. pulchella be R. ghardaqana? I have enough troubles separating this two species in the Red Sea. To tell the truth, I have NO criteria to distinguish them, "large" or "larger" yellow spots might be anything, but no EXACT criteria.

Dear Erwin,
Sorry it's taken me a while to answer this. I haven't been ignoring it - its just taken a while to prepare. I had recently been thinking that these two 'species' had got out of control on the Forum and was in the process of trying to sort them out, so your message was timely. One of the advantages of having lots of photos on the Forum is that problems like this certainly can't stay hidden long. In a separate message, you will see I feel that most of the animals I have been tentatively calling R. ghardaqana on the Forum almost certainly R. pulchella.
Best wishes,
Bill Rudman
